i got this from surge, I was going to build another upper but am going to have to put this off to pay for books for summer semester. I believe that the the barrel only has 20 rounds through it so it is practically new, It was only tested for function befor MSTN started to customize the original rifle

I paid 200, i would like 175 for this,

barrel comes with, extension, and A2 falsh hider

the barrel is at my shop so unfortunatly i can not provide any pics, Email or IM with any question
